Description

Technical Field

[0001] This utility model relates to the technical field of material weighing systems, specifically a material weighing system integrated inside a tank truck. Background Technology

[0002] Material metering management has always been a key focus of the industry during tank truck transportation operations. The commonly used weighing solution is to set up a weighbridge system at a fixed location and calculate the net weight of the material by measuring the total weight of the tank truck. This static weighing method requires a dedicated weighing platform, sensor system and data processing terminal, forming a standardized weighing operation process.

[0003] The process of weighing materials in tank trucks using external weighbridges is cumbersome, makes it impossible to monitor loading status in real time, and can easily lead to vehicle overloading, posing safety hazards. Furthermore, the limited availability of fixed weighbridges makes accurate weighing difficult in remote areas or temporary work sites, restricting operational flexibility. Therefore, we propose a material weighing system integrated inside the tank truck. Utility Model Content

[0004] The purpose of this utility model is to provide a material weighing system integrated inside a tank truck, in order to solve the problems mentioned in the background art, such as the cumbersome operation process of external weighbridges, the inability to monitor the loading status in real time, the easy occurrence of vehicle overloading, the existence of safety hazards, the difficulty in achieving accurate measurement in remote areas or temporary work sites due to the limited distribution of fixed weighbridges, and the limited operational flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material weighing system integrated inside a tank truck, comprising: a tank body, a weighing mechanism inside the tank body, a weighing plate and a weighing sensor inside the weighing mechanism, the weighing mechanism weighing the material in real time after the material enters the tank body, a sealing mechanism on the weighing mechanism, a sealing strip inside the sealing mechanism, the sealing mechanism controlling the sealing strip to always fit against the inside of the tank body and monitoring the wear condition of the sealing strip.

[0006] The weighing mechanism includes a fixed base plate fixedly connected to the inner surface of the bottom of the tank. The fixed base plate is fixedly connected to the weighing sensor. The weighing sensor is fixedly connected to a mounting base. The mounting base is fixedly connected to a load-bearing beam. The load-bearing beam is fixedly connected to a weighing plate. The edge of the weighing plate is provided with a sealing mechanism.

[0007] The sealing mechanism includes a sealing groove on the edge of the weighing plate, a compression joint fixedly connected inside the sealing groove, the compression joint fixedly connected to the sealing strip, the sealing strip slidably connected to the sealing groove, a reserved groove on the lower inner surface of the sealing groove, a telescopic spring fixedly connected inside the reserved groove, a pulley seat fixedly connected to the telescopic spring, a rotating shaft fixedly connected to the pulley seat, a pulley rotatably connected to the rotating shaft, the pulley slidably connected to the sealing strip, and a micro switch fixedly connected inside the reserved groove, the micro switch movably connected to the pulley seat.

[0008] The upper surface edge of the weighing plate is provided with a flow-guiding chamfer.

[0009] The load-bearing beams are equipped with reinforcing ribs.

[0010] The outer surface of the sealing strip has anti-slip texture.

[0011] This utility model has at least the following beneficial effects:

[0012] In use, this utility model achieves real-time and accurate weighing of materials inside the tank through a direct force transmission structure between the weighing plate, the load-bearing beam, and the weighing sensor, thus improving loading and unloading efficiency. It employs a sealing mechanism with automatic compensation function, where a telescopic spring continuously pushes the pulley and sealing strip against the tank wall, forming a reliable dynamic seal. This effectively prevents material leakage and automatically compensates for wear gaps in the sealing strip, ensuring long-term sealing reliability. When the sealing strip wears to its limit, an alarm is automatically triggered, enabling preventative maintenance of key components and avoiding sudden malfunctions caused by seal failure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a material weighing system integrated inside a tank truck, comprising: a tank body 1, a weighing mechanism 2 installed inside the tank body 1, the core components of the weighing mechanism 2 including a weighing plate 21 and a weighing sensor 24. When material enters the tank body 1 through the feed inlet, the material directly accumulates on the upper surface of the weighing plate 21. The weighing plate 21 transmits the weight of the material it bears to the weighing sensor 24 through the load-bearing beam 22 and the mounting base 23. The weighing sensor 24 converts the pressure signal into an electrical signal in real time and outputs it, thereby realizing real-time and dynamic weighing of the material inside the tank. To ensure that the weighing process is not disturbed by external factors and to prevent material leakage, a sealing mechanism 3 is specially provided on the weighing mechanism 2. The sealing mechanism 3 has a sealing strip 32 inside. Its unique feature is that it can control the sealing strip 32 to always be tightly attached to the inner wall of the tank body 1 through the internal mechanical structure to form a dynamic seal, and automatically send a monitoring signal when the sealing strip 32 is worn to the point that it needs to be replaced.

[0021] The weighing mechanism 2 includes a fixed base plate 25 fixedly connected to the inner surface of the bottom of the tank 1. The fixed base plate 25 serves as the basic support for the entire weighing system. The upper surface of the fixed base plate 25 is fixedly connected to the weighing sensor 24. The upper output shaft of the weighing sensor 24 is fixedly connected to the mounting base 23. The upper part of the mounting base 23 is fixedly connected to the load-bearing beam 22. The upper surface of the load-bearing beam 22 is fixedly connected to the weighing plate 21 to form a rigid structure. The weight of the material is transmitted to the weighing sensor 24 in sequence through the weighing plate 21, the load-bearing beam 22, and the mounting base 23. The strain gauge inside the weighing sensor 24 deforms and generates an electrical signal. After processing, the signal is displayed on the display screen in the cab, allowing the operator to monitor the loading amount in real time. To prevent material leakage from the gap between the weighing plate 21 and the tank 1, a sealing mechanism 3 is provided at the edge of the weighing plate 21.

[0022] The sealing mechanism 3 includes a sealing groove 31 formed on the edge of the weighing plate 21. A compression joint 33 is fixedly connected inside the sealing groove 31 by a snap fastener. The compression joint 33 is made of corrosion-resistant rubber material and has good elastic recovery performance. The outer end of the compression joint 33 is fixedly connected to a sealing strip 32, which is made of wear-resistant material and can slide within the sealing groove 31. A reserved groove 34 is formed on the lower inner surface of the sealing groove 31. A telescopic spring 35 is fixedly fixed inside the reserved groove 34. The upper end of the telescopic spring 35 is fixedly connected to a pulley seat 36. A rotating shaft 37 is fixedly connected to the pulley seat 36 through a bearing. A pulley 38 is rotatably connected to the outside of the rotating shaft 37. The pulley 38 forms a sliding connection with the lower surface of the sealing strip 32. In the initial state, the telescopic spring 35 is in a compressed state, and the pulley 38 pushes the spring into the lower surface of the sealing strip 32. The sealing strip 32 applies a continuous upward thrust, keeping it in close contact with the inner wall of the tank 1. As the usage time increases, the sealing strip 32 gradually wears down. The telescopic spring 35 pushes the pulley seat 36 upward to compensate for the wear gap. The micro switch 39, which is fixedly installed in the reserved groove 34, is always pressed against the pulley seat 36. When the sealing strip 32 wears to its limit, the pulley seat 36 is ejected from the reserved groove 34, the micro switch 39 pops out, triggering the alarm circuit and sending a signal to the operator to replace the sealing strip 32. This achieves the automatic monitoring function of the wear condition of the sealing strip 32.

[0023] Example 2

[0024] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the upper surface edge of the weighing plate 21 is provided with a flow guide chamfer 4. The flow guide chamfer 4 effectively solves the problem of material residue at the corners, ensuring complete unloading and reducing cleaning workload. The connection of the load-bearing beam 22 is provided with a reinforcing rib 5. The reinforcing rib 5 enhances the connection rigidity between the weighing mechanism and the tank, effectively dispersing dynamic loads and improving the service life of the system. The outer surface of the sealing strip 32 is provided with anti-slip texture 6. The anti-slip texture 6 prevents the sealing strip from sliding by increasing the friction coefficient, which can reduce the wear rate.
